Thermostatic Mixing Valves (TMVs) in Aged Care facilities are subject to local regulations and standards such as AS/NZS 4032.3:2016, ensuring they mix hot and cold water to maintain safe outlet temperatures typically between 38°C and 45°C, crucial for preventing scalding among vulnerable residents. 

Installation, maintenance, and documentation must align with regulatory requirements, with qualified plumbers responsible for installation and periodic maintenance to ensure proper functionality. 

Staff training on TMV operation and response procedures to temperature-related incidents is essential, as is conducting risk assessments of water systems to identify and mitigate potential hazards, ultimately safeguarding resident safety and compliance with regulations.
